[0002] At present, in the domestic cotton ring spinning system, the roving process has a great influence on the yarn quality and the subsequent spinning efficiency. The essence of roving is to draw out and lengthen the cooked yarn, give it a certain twist to form roving, and wind it into a double-conical cylindrical package suitable for feeding into the spinning frame. Usually the roving frame includes two working parts, each of which includes a spindle wing and a bobbin. The center of the spindle wing is provided with a rotating shaft, and the bobbin is installed on the rotating shaft; the spindle wing is to introduce the yarn output by the front roller of the roving frame into the false twister, pass through the closed yarn guide tube, and then wrap it around the pressure palm for several turns, and then wind it on the yarn tube that reciprocates up and down to form a tube of a certain shape for use in the next process.

[0003] During the spinning process, the fiber raw materials with high chemical fiber content will quickly accumulate a large amount of static electricity after rubbing against the spindle, causing the fibers to repel each other and produce flying fibers. Flying fibers will cause uneven yarn and damage the health of workers. Utility Model Content
